All (3) of the triangles are similar to one another, and they have the 30-60-90 interior-angle pattern. This allows us to establish the following relations.

a+b=2x\implies x=\dfrac{15}2


z=\sqrt3\,x\implies z=\dfrac{15\sqrt3}2


\dfrac ax=\dfrac x{a+b}\implies a(a+b)=x^2\implies15a=\dfrac{15^2}{2^2}\implies a=\dfrac{15}4


a+b=15\implies b=15-\dfrac{15}4=\dfrac{45}4


y=\sqrt3\,a\implies y=\dfrac{15\sqrt3}4

Harmony earns 42,000 salary in the first year of her career. Each year, she gets a 4% raise. Which expression gives the total am
kiruha [24]

Answer:

A=42000(1.04)^n

Step-by-step explanation:

This is a compound interest formula expressed as:

A=P(1+i)^n

Where

  • n is time in years
  • i is the rate of interest
  • A is the accumulated amount after n years
  • P is the initial amount.

#We substitute the given values to determine amount after n years as follows:

A=P(1+i)^n\\\\=42000(1+0.04)^n\\\\=42000(1.04)^n

Hence, the amount earned after n years of her career is given by A=42000(1.04)^n
